SPECIFICATION forrning part of Letters Patent No. 523,729, dated u ly 31, 1894. Application filed Mach 11,1893. gain 110,465,541. (Numan.)

To aZZ whom t may concern: y

Beit known that I, FRANK P. PELEcuLAE,A

, a citizen of the United States, and a resident of the city and county of Newaven, State of Connecticut, haveV invented a new and useful Apparatus for Clamping and Securing in Position Peripheral Bands on Polishing or other Wheels, of which the following description, taken in connection with the drawings herewith accompanying, is a specification.

My invention has for its object to provide a cheap and simple device or means for stretching and clamping the peripheral bands of polishing wheels upon the supporting Wheel or disk and securing the ends of the same.

' The invention consists in the construction and combination of the parts forming such device as will hereinafter be set forth Vin detail and pointed out the claims.

Referring to the drawings:-Fig'ure 1, represents my new device in position upon a polishing wheel, showing the ends of the band brought into position to be forced into .thel

opening in the disk. Fig. 2, represents a plan view of the same. Figs. 3 and 4 represent vertical sectional views through the opposite ends of the clamping band and theends of their connecting frame or device, to more clearly show the construction ofthe same.

To explain in detaiL-a represents a polishing wheel, and a its peripheral band. The said disk being provided in the instance shown, with an opening or groove (12in its periphery into which the ends of the band a are adapted to be extended and secured in a manner as set forth in my said pending application above referred to.

l The device forming my present invention,

for securing the baud a. on its supporting disk or wheel, consists of a flexible 4band 5,'

preferably formed of metal, which is adapted to embrace the periphery of the disk as more clearly shown in Fig. l, and is provided with a raised shoulder or projection b at each end thereon, forming abearin g surface for the connection or engagement therewith of a frame cwhich latter engagesat one end with one of the shoulders b as more clearly shown in Figs. 2 and 3, and at its opposite end is pro i vided with an adjusting screw b2 supported 5o therein, which is adapted to engage with the shoulder on the opposite end of the band b, (as clearly shown in Figs. l, 2 and t)'in such manner that Athe operator by turningsaid screw may cause the ends of the band h to draw toward each other and thus stretch the peripheral band a uponvthe disk or wheel a and force the ends of the same toward each other and in position to be forced into the opening or groovev a,2 in the disk adapted to 6o receive the same. When the ends of the peripheral band are thus brought together and held in aposition to be inserted intjothe opening a in the disk, as shown in Fig. 1, they are adapted to be forced into the latter by means of a vertically movable vplate CZ which-is supported on the end of an adjusting screw d by which it is operated to be lowered or moved downward-to engage with the band lot and. force the turned-in ends of the sameinto the opening or groove in the disk or Wheel a in which they are held. lThe adjusting screw d is supported and operates in a part c of an 'extension c2 ot' the frame c as shownfin Figs.

land 2. The frame c is provided with another extension c3 upon the side opposite that of the part c2 and in line therewith, which is also provided with an adjustable plate or block c4 supported and operated by an adjusting screw c5, which saidplate orblock is adapted to' engage with the lower or opposite edge of the wheel to form a bearing against y which the opposite compressing plate ol may act or draw when being operated to force they ends of the band a' into their said receiving openingen2 in the diskor wheel a. The plate or block c4 being thus adjustable also allows the device to be properly adjusted to Wheels or disks of different sizes asiwill bereadily understood. l.

Having thusset forth myinvention, it will be obvious ,that various changes may be made 'in the construction and arrangement of the several parts of the device Without departing from. the spirit of my invention. For instance, cam levers might be used in lieu of the adjusting screws shown, for operating the severalconnecting or engaging parts, or the manner of connecting and supporting the several parts in their relation to each other be varied; but s What I do claim, and desire to secure by Letters Patent of the United States, isl 1. An apparatus for clamping and securing in position the peripheral band on polishing or other wheels, consisting of a flexible band, and the frame or device c for engaging or connecting the ends of said band, provided with means for drawing together or moving the same in their relation to each other, substantially as described and for the purpose set forth. p

2. An apparatus consisting of a flexible band, a frame for connecting the ends of said band, provided with means for moving the Same in their relation to each other, and a movable plate with means for operating the same, substantially as described and for the purpose set forth.

3. An apparatus consisting of a flexible clamping band, and a frame provided with means for connecting the ends of said band, a movable clamping plate, and a bearing surface for contact with the polishing wheel or other body against which the said clamping plate may draw when operated, substantially as described and for the purpose set forth.

4. An apparatus consisting 'of a iexible band, a frame provided with means for connecting the ends of said band, a movable clamping plate, and an adjustable bearing plate or surface, arranged and operating in their relation to each other in a manner Substantially as described and for the purpose set forth.

5. An apparatus consisting of a flexible band provided with raised shoulders or bearing surfaces at its opposite ends, and a frame or device forming a connection between said shoulders or bearing surfaces provided vvvith au adj usting-screw for moving the ends of the band in their relation to each other, substantially as described and for the'purpose set forth. p p
